BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention relates in general to a cradle, and more particularly to a cradle capable of placing an object in alternative size.

[0004] 2. Description of the Related Art

[0005] The hand-held computer for commercial or personal purpose typically functions as a cellular phone, fax sender, and personal organizer. Users can easily get information on demand due to the portability, compactness and friendly interface of the hand-held computers. Besides, various accessories to the hand-held computer are designed to create additional functionality.

[0006] For example, the jacket is an accessory, which not only provides a good protection but also makes the hand-held computer more flexible. Users can add PCMCIA (Personal Computer Memory Card International Association) card or CF (Contact Flash) card to the hand-held computer for additional functionality by inserting the interface card into the jacket to satisfy their individual need. Thus, a hand-held computer with a jacket has become an alternative choice for consumer.

[0007] However, the hand-held computer with a jacket is bigger than that without a jacket. It cannot afford to utilize the additional functionality of the jacket efficiently since the jacket used to be taken off while the hand-held computer is placed on the cradle. Besides, it does harm the hand-held computer by taking off the jacket repeatedly.

[0008] If the cradle is designed for the hand-held computer with a jacket in a larger size, it might cause negative effect of the battery charging quality or data transmission by simply placing the hand-held computer without a jacket on the cradle due to the unsteady connection.

SUMMARY OF THE INVENTION

[0009] It is therefore an object of the invention to provide a cradle capable of placing an object in alternative size firmly to avoid negative effect of battery charging quality or data transmission due to unsteady connection. The bi-directional data transmission can be proceeded by connecting with a computer host and the battery charging of the object can be proceeded by plugging in.

[0010] The invention achieves the above-identified objects by providing a cradle capable of placing an object in alternative size. The cradle includes a main unit, a slide mechanism and a lock mechanism. The main unit loads and holds the object. The slide mechanism has two slide members, which move along the insides of the arc blades of the body upwards or downwards, for adjusting the size of the room for placing the object. The lock mechanism positions the slide mechanism by clasping the slide mechanism. The port connected with the computer host for bi-directional data transmission with the object and the socket plugged in for battery charging of the object are disposed on the rear side of the body.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0018] Referring first to FIG. 1, an exploded view of a cradle according to a preferred embodiment of the invention is illustrated. The cradle includes a main unit, slide mechanism and lock mechanism. The main unit further includes a cap 108, body 110, and base 112. The top and bottom of the body 110 are coupled with the cap 108 and base 112 respectively. The cap 108 and body 110 are for holding an object while the base 112 is for loading and fixing it. The slide mechanism capable of adjusting the size of the room for placing the object includes two slide members 100 and two slide springs 106. The slide springs 106 are coupled with the bottom of the slide members 100. The lock mechanism positions the slide mechanism by clasping the slide mechanism. The lock mechanism includes a slide lock 102 and a slide lock spring 104. The slide lock spring 104 is capable of holding the slide lock 102 for restoring or sustaining the slide lock 102 in a fixed position. The slide lock 102 has a first and second claspers 104, a beam 118, and a push-button 116. The first and second claspers 104 are disposed at two ends of the beam 118 respectively and the push-button 116 is disposed on the beam 118.

[0019] Referring to 2A˜2B, the cutaway side views of a cradle with a lock mechanism clasped and unclasped according to the preferred embodiments of the invention are shown. The slide member 100 is disposed inside the cradle body 110 and contacts the arc blade 202. The slide member 100 moves along the inside of the arc blade 202 and drags the slide spring 106 upwards or downwards. As shown in FIG. 2A, the slide member 100 starts the lock mechanism when the slide member 100 moves downward along the inside of the arc blade 202 by an external force. The clasper 114 locks the slide mechanism by clasping the bottom of the slide member 100.

[0020] As shown in FIG. 2B, the slide lock 102 rotates around the beam 118 and the clasper 114 moves downward to unlock the slide mechanism by unclasping bottoms of the slide member 100 while a push-button 116 is pressed. The slide member 100 subsequently moves along the inside of the arc blade 202 upwards by elastic power of the slide spring 106 after compression. It then restores the cradle with a lock mechanism unclasped.

[0021] Referring to FIG. 3, a rear view of a cradle according to a preferred embodiment of the invention is shown. The first and second slide members 100 a and 100 b are disposed on two sides of the cradle body 110 and contact the first and second arc blade 202 a and 202 b respectively. As shown in FIG. 3, a port 302 and a socket 304 are disposed on the rear side of the body. When the object is placed on the cradle, the object can be connected with a computer host for bi-directional data transmission, which makes the transmission between the object and computer host synchronous. The computer host can be a desktop computer or a notebook computer while the socket can be a serial port or USB port. The object can also be battery charged through the connection of the power plug 304 and power supply. Besides, the bi-directional data transmission and the battery charging of the object can be proceeded simultaneously. The push-button 116 is located at the joint of the cap 108 and the cradle body 110. After pressing the push-button 116, the lock mechanism is then restored. The strut 306 on the upper surface 300 of the cap 108 holds up the object to avoid the failure in battery charging or data transmission due to the shaking.

[0022] Referring to FIG. 4A˜4B, a perspective view of a cradle inserted by a hand-held computer and a cradle inserted by a hand-held computer with a jacket according to the preferred embodiments of the invention are shown. As shown in FIG. 4A, the first and second slide members 100 a and 100 b contacts the first and second arc blades 202 a and 202 b on two sides of the cradle body 110. The hand-held computer 400 is steadily placed on a first seat formed by an upper surface 300 of the cap 108, the first and second slide members 100 a and 100 b.

[0023] Referring to FIG. 4B, the first and second slide members 100 a and 100 b move downward along the insides of the first an second arc blades 202 a and 202 b when the hand-held computer 400 with a jacket 402 is inserted. The hand-held computer 400 with a jacket 402 is steadily placed on a second seat formed by the upper surface 300 of the cap 108, the first and second arc blades 202 a and 202 b.

[0024] The cradle capable of placing an object in alternative size according to the invention secures the hand-held computer by selective sliding of a pair of slide members. It can also provide the cradle with multiple selection for placing objects in different sizes by selective sliding of plural pairs of slide members without departing from the spirit and scope of the invention.

[0025] The cradle according to a preferred embodiment of the invention is able to secure the hand-held computer in alternative size firmly and avoid negative effect of battery charging quality or data transmission due to unsteady connection. The hand-held computer with a jacket can be inserted onto the cradle. It therefore avoids harming the hand-held computer by taking off the jacket repeatedly. Moreover, it is convenient that the bi-directional data transmission with a computer host and the battery charging of the object can be proceeded simultaneously.
